The utility model discloses an actuating mechanism capable of simultaneously opening and closing two valves. The actuating mechanism comprises a first gear and a second gear, wherein the first gear is installed on a first valve rod, and the second gear is installed on a second valve rod. The actuating mechanism is characterized in that the first gear and the second gear are positioned inside a gear box; simultaneously, a driving gear respectively meshing with the first gear and the second gear is further installed inside the gear box through a spindle; and one end of the spindle is exposed out of the gear box to serve as an operation end. When the actuating mechanism is used, the first gear and the second gear can be conveniently driven to rotate by driving the operation end of the spindle, namely, the valve rods of the two valves can be driven to rotate by only by a single operation, so that opening and closing action of the two valves can be simultaneously finished. Therefore, the actuating mechanism is simple in operation and is not easily misoperated, is more flexible in installation and wider in application occasions as the driving gear is used for transferring power, and is particularly used on a sampler to lead a sampling process to be more simplified, thereby being capable of obviously improving operation convenience and reliability.
Description
Technical field
The utility model relates to a kind of actuator of valve, specifically refers to a kind of actuator that can open and close two valves simultaneously.
Background technique
Valve actuator is a kind ofly to utilize power to go actuate valve stem and reach and open or the device of throttle down, is an important structure assembly of valve.When valve group of several valves composition requires to cooperate the situation of work, then often need one by one the actuator of each valve to be operated, just need use a plurality of valves such as employed sampler in the chemical industry, as shown in figure 10, this sampler is when off working state, airtight sampler is connected in the whole process flow, the center-aisle of two three-way valve and left channel are connected, medium from import through the first three-way valve 1a, fixed volume canister 22, flow out from outlet behind the second three-way valve 2a, medium is in flowing state all the time, has guaranteed the ageing of sample.And the sampling process of this sampler is:, successively with the first three-way valve 1a, the second three-way valve 2a is Rotate 180 ° respectively, at this moment, the center-aisle of two three-way valve and right channel are connected, fixed volume canister 22 is cut out systematic pipeline, simultaneously nitrogen system is cut, nitrogen is through reduction valve 24, the second three-way valve 2a enters fixed volume canister 22 and sampling needle, medium flows in the sampling bottles 23 from fixed volume canister 22, treat that sample in the fixed volume canister all flows into sampling bottle after, successively with second three-way valve, 180 ° of first three-way valve difference opposite spins are incorporated the fixed volume canister into pipeline.Obviously, in above-mentioned sampling process, need the operating grip of each three-way valve of multi-pass operation, operating procedure is many, and each handle will operate in order, and misoperation takes place easily, if the operator has general idea will cause the sampling failure slightly.
At present, though also there is patent documentation to disclose the actuator that to operate two valves simultaneously, as Chinese patent notice of authorization number for " the interlock primary ﹠ secondary valve " of CN2416315Y just disclosed so a kind of valve group that can open simultaneously, main-valve in this primary ﹠ secondary valve and sub-valve are fixed together by link, onesize gear all is equipped with in the valve rod end of two valves, by the rotation realization main-valve of gear and the interlock of sub-valve, reach the purpose of controlling two pipe switchs simultaneously.But two pitch wheel structures cause the spacing between the primary ﹠ secondary valve less, and the application is restricted, and this model utility can not carry out spacingly to handle, are difficult for the opening state of support control two valves.Be not suitable for the application on the sampler yet.
The model utility content
Technical problem to be solved in the utility model is at above-mentioned prior art, and provides a kind of simple to operate, the same actuator that can open and close two valves simultaneously that is difficult for taking place misoperation.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: this actuator that can open and close two valves simultaneously is arranged on second valve rod of first valve rod of first valve and second valve, comprise first gear that is installed on first valve rod and second gear that is installed on second valve rod, it is characterized in that: described first gear and second gear are positioned at gear-box, in this gear-box, also be equipped with respectively and described first gear simultaneously by main shaft, the driving wheel that second gear is meshed, and described main shaft one end is exposed to outside the described gear-box and becomes the operating end.
In such scheme, this main shaft can be pulled by instrument, perhaps drives by modes such as motors.But mode is the handle head that the band handle is installed on the operating end of described main shaft comparatively easily, and the surface of contact between this handle head and the described gear-box is provided with the spacing indication piece of valve opening position.Utilize this spacing indication piece can make things convenient for, know intuitively the unlatching situation of valve.
Described gear-box generally is made up of casing and case lid, wherein case lid preferably contacts with described handle head, above-mentioned spacing indication piece can be realized by the mode of arrow, index line, but preferred version is: the sector region that has depression on this case lid, and on the handle head, being provided with the protuberance that matches with this sector region, this protuberance is inconsistent and form described spacing indication piece with two edges of described sector region respectively.Like this in when operation, without vision, opening state that also can the perception valve, it is convenient to operate.
In above-mentioned preferred version, when described two valves adopt three-way valve, closed condition for perception two valves, in the sector region of described case lid, can also have a locating slot, and in the protuberance of described handle head, has spring chamber, spring one end is against in the spring chamber, and the other end offsets with the hoodle that part is exposed to the protuberance surface, and this hoodle is corresponding with described locating slot and match with described locating slot.When handle with sleeve to two valve is in closed condition following time, the exposed portions serve of hoodle just in time is embedded in this locating slot, so that operator are in time known the closed position of valve.
Compared with prior art, advantage of the present utility model is: by the operating end of drive main spindle, can drive first, second gear easily rotates, as long as promptly carry out the valve rod rotation that once-through operation just can drive two valves, and then the open and close that can finish two valves are simultaneously moved, as seen the utility model is simple to operate, be difficult for taking place misoperation, and by the driving wheel transferring power, install more flexible, the application is more extensive, especially uses on sampler, makes sampling process simplify more and can improve operation convenience and reliability significantly.
